I can't properly sync case rgb with signalrgb, any tips?

I have the sharkoon mk6 case and the S90 RGB liquid cooler with the adressable rgb fans and i can't control every individual fan with signalrgb.

I have temporarily daisy chained the AIO and pump rgb so that it works as a single fan and connected it to the second rgb header and did the same thing with the case fans, connecting them to te first rgb header on the mobo.

Behind the case i have the rgb and fan header shown in the photo, the LED1 connector is were i should have connected the cooling rgb but, as said before, i connected it to te mobo; the LED2/3/4 headers connect to the 3 case fans, i connected them to the mobo using the third connector starting from the right(it splits in 2 cables because one goes to the case button used to control the rgb and the other to the mobo).

I want to control every fan individually, should i buy an argb hub (termalright/asianhorse/etc) so that i can plug every fan in it, or is it another way of doing it?

If there are some things that you don't understand sorry in advance, english isn't my first language, if there are any problems let me know.
